What this shows QLM's Innovation Score is 47.5/100 (top 18% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for QLM?

Each dot is one of QLM’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). QLM’s own 18.2 claims/patent is ABOVE the 16.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where QLM's grants concentrate

QLM Technology Ltd is a focused PatentsView assignee: 6 CPC subclasses with 88.9% of grants classified under G01S (Radio DIRECTION-FINDING; Radio NAVIGATION; Determining Distance OR Velocity BY USE OF Radio WAVES; Locating OR Presence-detecting BY USE OF THE Reflection OR Reradiation OF Radio WAVES; Analogous Arra). Peak complete grant year is 2024 (4 grants) versus a trough of 2 in 2023. By volume, QLM sits between Qatar Tourism and Quantum Biosystems Inc..

QLM's three-year grant acceleration

QLM Technology Ltd shows 6 grants in 2022–2024 against only 0 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
